After some research, I found out the Windows login Spotlight backgrounds are saved in the folder: %LOCALAPPDATA%\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets\. But each background is stored twice, one vertical and one horitzontal picture, I’d only need the horizontal for desktop backgrounds.
I created the PowerShell script below to copy the horizontal pictures from the Spotlight folder and copy into a Spotlight folder within the users Picture folder. Next, the desktop wallpaper settings can be pointed to this %userprofile%\Pictures\Spotlight folder to use as filled slidedshow.
Function Get-ImageDetails2
{
begin{
[System.Reflection.Assembly]::LoadWithPartialName("System.Drawing") |Out-Null
}
process{
$fi=[System.IO.FileInfo]$_
if( $fi.Exists){
$img = [System.Drawing.Image]::FromFile($_)
$img.Clone()
$img.Dispose()
}else{
Write-Host "File not found: $_" -fore yellow
}
}
end{}
}
Function DirectoryToCreate($DirectoryToCreate) {
if (-not (Test-Path -LiteralPath $DirectoryToCreate)) {
try {
New-Item -Path $DirectoryToCreate -ItemType Directory -ErrorAction Stop | Out-Null #-Force
}
catch {
Write-Error -Message "Unable to create directory '$DirectoryToCreate'. Error was: $_" -ErrorAction Stop
}
"Successfully created directory '$DirectoryToCreate'."
}
else {
<#"Directory $DirectoryToCreate already existed"#>
}
}
DirectoryToCreate("$env:USERPROFILE\Pictures\Spotlight\")
Function Get-ImageDetails
{
begin{
[System.Reflection.Assembly]::LoadWithPartialName("System.Drawing") |Out-Null
}
process{
$file=[System.IO.FileInfo]$_
if( $file.Exists){
$fs = New-Object System.IO.FileStream ($file.FullName, [IO.FileMode]::Open, [IO.FileAccess]::Read, [IO.FileShare]::Read)
$img=[System.Drawing.Image]::FromStream($fs)
$fs.Dispose()
$img | Add-Member `
-MemberType NoteProperty `
-Name Filename `
-Value $file.Fullname `
-PassThru
}
}
end{}
}
dir "$env:LOCALAPPDATA\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets\" -Recurse | % {
$image = $_
$imagePath = $image.PSPath
$imageName = $image.Name
$imageDetails = $image| Get-ImageDetails
$imHeight = $imageDetails.Height
$imWidth = $imageDetails.Width
if (($imHeight -le $imWidth ) -and ($imWidth -gt 1000)) {
copy-item -path "$imagePath" -destination "$env:USERPROFILE\Pictures\Spotlight\$imageName.jpg"
}
}
Using a Windows Scheduled task, the script can be run after every login. In order to make sure no PowerShell command window is shown for each execution, I created the little .vbs script to run the PowerShell in a hidden mode.Set objShell = CreateObject("WScript.Shell")
objShell.Run "CMD /C START /B " & objShell.ExpandEnvironmentStrings("%SystemRoot%") & "\System32\WindowsPowerShell\v1.0\powershell.exe -windowstyle hidden -file " & "spotlight.ps1", 0, False
Set objShell = Nothing
This .vbs file can be launched from the Windows Task Scheduler:
